L 1, uhm. it may concern: itilmown that I, BoYnDAUGnnRrY; a oltlgen ofthe United States, and a resident of Chicago, in the county ofCook and State of Illinois, have invented certain new and useful Ina rovements in- Grain-Car Doors, of whicht e following is a specification. g lhis invention relates to improvements in v grzsi 'in car doors in which the doorway is to closed wholly or partly by independently- Iri'dvable sections in fixed sliding-ways, which il, whennot in use are supported behe roofofthe car.

or grain car-door structures, such as eferred tqthe grain or other comstoregl in the car must 'first be shovsleds. the door and then the several sections liftd-toapoint adjacent to the roof before the/ doorway can be entirely cleared, all of iic involves manual labor, time, and

'Th bjectpfmyinvention is toprovidea closure-forja doorway of grain-cars made up of any number, of sections partly or-wholly 2.5 closing the doorway, which closure may be swung-to an open position or against the roof ot the "car -[without disturbing any of said sections and so constructed that the load adjacent thedoorway may be conveniently 3o and' 'qiiicklyidischarged adjacent the bottom thereof? v ,1With these ends in view'my invention cons'ist s in certain features of novelty in the con- -structioii, combination, and arrangement of. 3 5'parts ,byi Which ,the said objects and certain 0th r jobje'cts hereinafter appearing aro at- M all'as fully described with reference to'the accompanying drawings and more particularly pointed out in the claims. i n isaid drawings, Figure 1- represents a so section through a freight-car, illuslngj lg closures; embracing 'my invention,

The lower end of the channel bars 1.9 is sufficiently enlarged at.21 to enable the supplemental door-sections to pass around the necessary curve or angle between those bars and the side bars of the door.

As a convenient means of maintaining the door-sections from accidentally passing by gravity from the channel-bars 19mm the channel-bars 12 a pivoted gravitystopZZ is arranged across the path of movement of said bars; which said stop is preferably in the form of a gravity-hook,wh1ch, as shown, will be pushed'out of the way when the door-sec tions are shoved upwardly against it and 'yvhich will swing by gravity across the path said sections as soon as they have passed beyond the point of the hook, and therefore in a position automatically locking the doxvn-' ward movement of'said sections.

I n'the operation'jf'of my invention when filling a car with grain or other small ma'te rial the doors are swung to a' closed position and locked through the medium of the bolts 14 and 15, which to that end are forced by the eccentrjc into corresponding openings respectively in the sides of the door-frame and the floor of the car; Either before loading,

' but preferably as the loading progresses and the bulk of materials being loaded seems to require it, the door-sections 20, as needed for confining the grain, are moved downwardly to a positionnext above the door 13 and to each other, as may become necessary to prethe car and, in "box-car vent the materials escaping from the car, the number of said sections being, as before stated, sufficient to close entirely bothdoor- Ways, and especially when the car is used for materialoranerchandiseof. any kind, making it desirable to entirely close the doorways of fact, convert it into a closed In the operation of unloading grain or other fine particles from the car the discharge therefrom is quickened and facilitated owing to the top hinging ofthe door and the ability to swing the door outwardly away from the bottom or iioorof the car, and to which end I it is only necessary to release the bolt and "ordinarilyto utilize the gravity of the mate-- rials for forcing the door open." Furthermore, by this outward bottom opening of the car-door the facility 'forshoveling materials remote therefrom is very much increased,

and particularly'as compared with grain-car doors now commonly employed and in'which the bottom section cannot be opened until all other sections have been one at at'ime elevated above the same, which not onl rehand, 18th day of November,' 1905:."

q uires fgnabut severe manual labo 1 f,-w olly avoided by the structure of my invention. Again, the top hinging of the-door provides for swinging it inwardly out 'of' the Way against the roof of the car, and this without transferring any of the door-sections to the grooved way in the roof, and as a result of which said doors 'may be swung inwardlyv out oftheway before any substantial part of the entire load is discharged from the car and in a conditionadapting it for asubsequent loadjacent thereto, but at the same-time to entirely move the door, beyond the doorway for clearing thesame in unloading and also for maintaining the doorways open and the door'entirely out of the way when not in use.

Having described my invention, what I- claim as new, and desire to secure by Letters 1. The combination with a grain-car of a doorthe side edges of which are composed of channel-bars pivoted toward their upper ends and free to swing inwardly and outwardly from the car, and a series of board sections removably fitting between said channel-bars for increasing and decreasing the closure of the door at will, substantially as described. -2.

I V r p 3. The combinationwith a gram-car, of a retained, substantially as door the side edg'esof which are composed of channel-bars pivoted toward their upper ends and free toswing inwardly and-out-- wardly-from the car, a series of board "sections removably fitting between said "channel-bars for increasing and fdecreasingthe closure of the door at will and roof channelbars registering with the a door channel-bars when the door is in a vertical 'position,- subf stantially as described.
